Gemini 4 Argon launches for hard coding, finance, legal and science tasks

Gemini 4 Argon: Built to solve your hardest problems

Google opened Gemini 4 Argon worldwide today for complex coding, finance, legal, cybersecurity and science work, through the Gemini API and subscription tiers. The API takes a unified 1M token limit across input and output, priced at $2 per million input tokens and $10 per million output tokens, with cached input tokens discounted 95%.

Why it matters: Google used Gemini 4 Argon to refactor Chrome's architecture across hundreds of files, cutting months of engineering work to weeks.
